+### Authentication
+Conduit supports multiple authentication flows when connecting to your Open‑WebUI:
+- **Username + Password**: Sign in directly against servers that expose a login endpoint. Credentials are stored securely using platform keychains.
+- **API Key**: Paste a server‑issued API token for stateless auth.
+- **Custom Headers**: Add headers during login (e.g., `X-API-Key`, `Authorization`, `X-Org`, or self‑hosted SSO headers) that Conduit will include on all HTTP/WebSocket requests.
